V snow REMOVEB.

Application filed. April 25,

My present inventionrelates to improvementsin snow removers of the automotive implement type designed for removing snow from streets, highways, roads, etc., and depositing the snow at the side of the roadway. The implement is designed for use with a tractor or truck, and in the present 'eX- emplification of the invention the implement is shown in connection with a tractor of standard type utilizing traction belts in the place of traction wheels. The firm-'- be disposed of at the side of the road.

Various changes may be made in the two rotary conveyers for adapting the implement to heavy or light duty in the removal of the snow, and for this purpose the rotary con veyers are made up of interchangeable,

standardized parts that permit the changes to be made with facility and convenience.

The invention consists in certain novel combinations and arrangementsof parts as will hereinafter to be more specifically set forth and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention and a modification thereof, wherein the parts are combined vand arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

of a main frame 3 of rectangular shape,

Asexemplified in the drawings the ime i which is of the required strength and well bolted and braced for the purpose of supporting the'two rotary conveyers and accessory parts.

Atthe' rear of the tractoi'the mainframe I is coupled'thereto by meansof a transverse draw bar 5.;at. the'endsjof which are provided two vertical plates '6, 6 each havinga vertical row or series of boltholes 7 to;

accommodate the pivot bolts 8. These pivot bolts 8 pass through end flanges 8 of the transverse draw bar 5-,,through. the vertical plates, and as in Figure 3, sometimes through the side bars of the main frame 1. The pivot bolts may be used in'connection with a selected hole? of theplates to adjust the main frame in desired position with relationto the drawbar5 and its tractor. rear end of the main frame is braced or strengthened by means of a longitudinally The disposed draw link 9 which is eoapiedby its pin to a bracket 11 on the transverse;

The driver of the implement or vehicle occupies theseat 13 located just above they conveyer I utilize a ground shoe 34L plvoted coupling bolt 14- that secures theurear draw bar to the tractor bracket 15'. At'the front of thei-tractor an attachingbracket 16 is provided, and a bolt 17 is passed-through this bracket and the front,., transverse bolster 18, from which extend. a pairi of diagonal braces-.19 ;to. the front: corners .of the main frame: H r

As best seen in Figure 6, the ends of the bolster- 18 are provided {with plates 20 and thesecplates' arelthe means oftsupporting the pair of caster wheels r21journaled in yokesi22 andprovidedwith spindles 23,;that are journale'din rhousings or. bearings- 24 fashioned at the endof the. end plates; Ball:

3 bearings are indicated a't ,.25 to facilitate freedom-of movement of the caster wheels, an d these-wheels at will beapparent are -.'for

the ,purpose of, supporting the front end of the inclined main frame, togetherv withv the two pivotal bolts ,8 at the. ends tofthe rear draw bar ofthe tractor,

Thegbolster is pivoted nthe .bracketi16" that is rigid with the tractor as is also the bracket 15 of-theirear draw bar 5, while the mainframe is pivoted on a transverselaxis,

i the springs are pivoted tohangers .30 on these suspension levers and the rear ends of the springs are pivotally connected to the leversby shackles l. 1 The: rear,.free ends vloft-the suspension leversmaygbe raised-or lowered to adjust the front-end of the main .f'ramewith relation to-the road surface, and

i v to 'of -themainframe.

for;(holding these I levers in. fixed adjusted position I utilize pawls32 forengagement with the rack bars 33 'fixed onthe side bars Across the frontzof the machine and supportedwinthe main; frame above the turned up or curved-front ends A, is a horizontal,

ii-transversely; 1 arranged screw conveyer: I 41 that turns anti-clockwise, as indicated by the arrow-i11 Figure l forconveying the snow fron1'--left to IlghtiLSHtl'lB implement advances along the roadway? If the snowis of comparatively light depth, only the transverselrotary co-nveyer is utilized, "as seen in Figure 8, but when the snow is ofgreater depth','both the transverse conveyer and the longitudinally;zdisposed conveyer are used for handling the snow.

In connection with the transverse rotary at its endsat 35" in -=thefront of the main frame and extending transversely from side i to side of thenframe, to form a'scoop or shovel forthe snow in co-action Wlilll' the rotary conveyeror screw 41. vBy meansof racklevers 37 'connected to the arms,; and:

rack bars ,38'fixed tothe main frame side bars, the scoop may be adjustedon its pivots oi hinges'35 and retained in adjusted p031 tion. Q At its rear the scoopis hinged to a i transversely extending I-bea1n39 byniean s of suitable brackets-,and the rear edge 34:

of the scoop overlaps thefront lower'end; ofthe guide plate 10. I 'This guide' 'plate whichis attached to theI-beam is of semiv cylindrical shape to conform to the shape of the screw conveyer 11 with which it 00- of. open center, or annular blades, is supg ported: 011:3.I1d revolves, with a horizontal shaft 42 "journaled in" bearingsfH-l of the mainframe,and thisshaft is driven through itssprocket wheel 44, chain 45, and sprocket wheeltlfi of the Inotor; t7, a clutch mechanism being indicated at 418 for controlling the operation of the-shaft Y I TheshaftA-FZ :is also used to operate the elevator-conveyer at the side of the implement through a gear couple comprising a bevel gear 19 on shaft: 64 {forming an GX tension of shaft 12, and gear 50 on section 64: of the rotary elevator shaftQthe, other sectio'nsof thisshaft being designated 51 and 55 Therotary-or screw elevator is madeup ofthree sections .as 52,152 and 53 which are separablejand their respective shaft sections 64 51 andt55 are also separableiordetachable and provided with slip couplingstindicated at 54, and .of course. the

ings as 56 Thescrew conveyer or elevator as bestvseelrin Figure 4 isnpartly enclosed with-an inclined hood 57, the latter being open toward:thenroad side and provided with a fiatchute or plate 58 overiwhich the snow is pushed by the spirally arranged or screw blades of the elevator. l

For packin glthe. snow-to prevent it falling to the vroad level afterbeingpushed over. the

chute 58,1 utilizea longitudinally extending plate 59 hinged beneaththechute58 at 60 and held in adjusted position by. means of braces or pawls 61 hinged or pivoted at the free edge of the plate 59, and these pawls or braces are held in proper position by springs 62 to engage a selected tooth of the rack 63 to retain the plate 69 in adjusted position for rubbing against the snow bank is added to the transverse hood 410 for co- I action with the added flight or section 52,

and the snow is conveyed to the right as the implement advances and pushed out at the right end of the hood 41066.

In some instances the length of the conveyer-elevator may be changed as by removing one of the sections, as 5.3 when not needed.

In Figure 9 the means of attaching or supporting the screw sections from their shaft sections is illustrated where clamp blocks 5O are secured about the shaft section (here shown as hollow or tubular) by means of bolts passed through a pair of straps 52 and the ends of these pairs of straps are rigidly attached at diametrically opposite points of the screw blade.

To facilitate the removal of the snow when it has reached considerable depth I utilize a series of oscillating shovels as 67 carried at the front ends of arms 68 that slide in guide bushings 69. The bushings are provided with angularly disposed sleeves 70 that oscillate on a cross bar 71 that forms part of a frame 71 rigid With the main frame. Each arm 68 has a bearing block or journal block 7 2 on the crank shaft 73, and this crank shaft is driven from the conveyer shaft 42by means of a sprocket wheel 74, chain 75, and sprocket 76 on the crank shaft. The crank shaft is journaled in bear ings 77 of the frames 71 above and a little to the rear of the rotary conveyer,.and the shovels 67 reach out in front of the rotary conveyer to pull in the snow toward the conveyer. By the action of the crank shaft the shovel end of the arms is caused to swing with the pivotal center 011 therod. or bar 71, and the movement of the crank bearing 72 of the arm is compensated for by the slide action of the rear end of the arm in the bushing 69, the parts being oiled as usual by means of oil cups as 78. The oscillating shovels are especially useful in breaking down a snowbank, as in a cut through which the road passes, and they shovel the snow onto or in front of the transverse conveyer so that the latter may convey it to the right side of the road.

The implement is steered by the movement ofthe tractor and the latter is steered in usual manner by the driver of thefvehicle, while the caster wheels of the main frame permit smooth movement of the frame and parts supported thereby; I K

Having thus fully described. my invention, what I claim as new and desire to secure by Letters Patent is j 1. In a snow remover the combination with an open main frame and conveyers thereon, of a tractor within the frame, a rear draw bar pivoted on the tractor and pivotal connection between said bar and the main frame, a front bolster pivoted on the tractor and caster wheels at the ends of said bolster, a suspensionframe comprising side levers pivoted to the main frame andmeans for securing the free ends of-said' levers to 'the main frame, suspension springs at the ends of the bolster, and pivotal connections at theends of said springs to said levers.
